A roulette wheel has 38 numbers: 1 through 36, 0, and 00. A ball is rolled, and it falls into one of the 38 slots, giving a winning number. Each bet lists the payout for winning on a $1 bet, including the dollar that was bet. Find the odds in favor of the bet, and the expected value. Express all ratios in lowest terms. Betting on an individual number: $29 The odds in favor of the bet are D. The data (in millions of dollars) are the values of 32 sports franchises in a given year. Construct a grouped frequency distribution for the data using seven classes. 1185 1038 1385 886 898 927 1234 1600 872 953 1173 1384 868 1471 1444 1097 1488 825 1412 960 1278 1322 1449 1467 1285 908 1097 1408 1499 1127 1451 1128 To construct seven classes, the range for each class (or the class width) should be [I].

The survey had a margin of error of 2.9% with a 95% condence level. What does this margin of error tell you about the percentage of people visiting this website who do not like the color red? We can be 95% condent that somewhere between D % and 0% of the visitors of this website do not like the color red. Question 4 of 1.1.
